Load Break Switch
Key Info
| Definition | : | A medium/high-voltage switch used to make or break normal load current safely. |
| Main Function | : | Switching and isolation of electrical circuits in power distribution. |
| Fault Current | : | Cannot interrupt short-circuit or fault currents (circuit breakers do this). |
| Arc Quenching Methods | : | SF₆ gas, vacuum, air/gas-generating, or oil. |
| Components | : | Operating mechanism, switching contacts, arc-extinguishing chamber, often HRC fuses for protection. |
| Common Types | : | SF₆ type Vacuum type Air / gas-generating type Oil-immersed type |
| Applications | : | Distribution networks Ring Main Units (RMU) Industrial plants Solar and wind power systems |
